Picked up a 2016 chevy volt battery W/ 38k miles last week for my 140kW VetteCart build (hopefully electric replica C2 Corvette one day).
This battery is beautifully made. I was really impressed with the designs and how easy it was to disassemble. Here are a few photos:
Battery after unloading. Excuse the huge pile of dirt on the floor. The garage door needs a new seal.
BMS and high-power wiring removed. I wish I'd documented the process better, but everything was neatly packaged and easy to remove. The connectors didn't put up much of a fight and nothing was damaged during disassembly which can be rare when dealing with modern cars.
Modules removed from the mounting plate. The gen 2 modules don't have the tacky adhesive that I heard about holding gen 1 modules in place. Instead they have grippy rubber strips under the hold-down bars, so there's no prying involved in removing them.
These are configured differently from the gen 1 modules. That was a little bit of a surprise to me, but it will work out better for my application anyway. Gen 2 batteries have three 16S3P modules and four 12S3P modules.
All the 12S and 16S modules were within less than 0.1V of each other. (I don't think I tried to measure at a higher resolution than 0.1V anyway)
Some of the goodies inside the connection block include this cool 20-600A (I think?) current clamp. If anyone has a couple of these lying around I'd be interested. I'm thinking I'll monitor the current being drawn from each of my parallel blocks independently.
Now comes the long process of figuring out how to best fit these in the car and working out the BMS.
